Answer to Question #123102 in Organic Chemistry for Alice Mico Symoni

Question

Calculate the mass of cucl2 that would be require to obtain 10.0g of pure copper

Answer 1

Let Mass of CuCl₂ is x gm .

so, moles of CUCl₂ is x / (63.5 +71). = x / 134.5

1 mole of CuCl₂ gives 1 mole of Cu ;

so, mole of Cu =( x / 134.5 ) mole;

mass of Cu = 63.5 x /134.5 = 10 ;

so , mass of Cu = x = 21.1811 g. answer.
